The Water Supply (Water Fittings) Regulations 1999 require irrigation systems in non-domestic settings to be separated from the incoming mains water supply using category 5 back-flow prevention.
The Access Cat 5 Pump and Tank Set provides compliance in a compact unit and can be configured to accept a number of different Lowara BGM pump units. The pump unit has an auto-start feature, so the pump will operate as soon as it detects a pressure drop in the system, for example opening a tap or solenoid valve.
Category 5 backflow is achieved using an approved Type AB air gap. As part of the specification for type AB air gaps, any overflow water must flow freely through the weirs in the tank. This must be taken into consideration when siting the unit.
